The aim of this study is to investigate the effectiveness of conceptual change text oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students’ misconceptions, their understanding of rate of reaction concepts and their attitude towards chemistry as a school subject. 42 tenth grade students from two classes of a chemistry course taught by the same teacher at a public high school in Çanakkale involved in the study. The study was carried out in Spring Semester of 2005-2006 Education Year. Two groups of students participated in the study. One group was called Experimental Group and instructed with conceptual change texts oriented instruction accompanied with analogies and the other group was called Control Group and was instructed with traditionally designed chemistry instruction over a period of four weeks. To investigate the effectiveness of the treatment, Rate of Reaction Concepts Test and Attitude Scale Towards Chemistry as a school subject were administered to both groups of students at the beginning and at the end of the treatment period. To evaluate students’ science process skills, Science Process Skills Test was administered to both groups of students before the treatment. MANCOVA was used to test the hypothesis of the study. The results of the study indicated that students instructed with conceptual change texts oriented instruction accompanied with analogies gained higher average scores in Rate of Reaction Concepts Test than the students instructed with traditionally designed chemistry instruction. Results and strategies that were developed for the present study may be used by science teachers to reduce and eliminate students’ misconceptions about rate of reaction concepts.

Effect of analogy-enhanced instruction accomponied with concept maps on understanding of acid- base concept Yılmazoğlu, Candan; Yılmazoğlu, Candan; Department of Secondary Science and Mathematics Education (2004) This study was conducted to explore the effectiveness of analogy-enhanced instruction accompanied with concept maps over traditionally designed chemistry introduction on understanding of acid-base concept and attitude toward chemistry as a school subject. 81 8th grade students from two classes of a chemistry course taught by the same teacher in Nuh Eskiyapan Primary School in Ankara in 2003-2004 fall semesters were enrolled in the study. There were two groups of students. During the treatment, students in t...
Facilitating conceptual change in learning rate of reaction concepts Bozkoyun, Yasin; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004) The main aim of this study to investigate the effectiveness of conceptual change texts oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students̕ misconceptions, their understanding of rate of reaction concepts and attitude towards chemistry as a school subject. 56 tenth grade students from two classes of a chemistry course taught by the same teacher in the ATATÜRK Anatolian High school, participated in the study. This study was carri...
Conceptual change text oriented instruction to facilitate conceptual change in atoms and molecules Günay, Barış; Geban, Ömer; Department of Secondary Science and Mathematics Education (2005) The main aim of this study to investigate the effectiveness of conceptual change texts oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students2 misconceptions, their understanding atoms and molecules concepts and attitude towards chemistry as a school subject . 45 tenth grades students from two classes of a chemistry course taught by the same teacher in Elmadag High School prticipated in the study that was carried out in 2004 62005 ...
Using the science writing heuristic approach to promote student understanding in chemical changes and mixtures Kıngır, Sevgi; Geban, Ömer; Günel, Murat; Department of Secondary Science and Mathematics Education (2011) The purpose of the present study was to investigate the effect of Science Writing Heuristic (SWH) approach on 9th grade students’ understanding of chemistry concepts and chemistry achievement in chemical changes and mixtures units. Four 9th grade classes taught by the two chemistry teachers from a public high school were selected for the study. Each teacher’s one intact class was assigned as the experimental group and the other class was assigned as the control group. Students in the experimental group were...
Exploring representation of nature of science aspects in 9th grade chemistry textbooks Esmer, Feyza; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011) The aim of this study was to examine the representation of Nature of Science (NOS) aspects in 9th grade chemistry textbooks. Two textbooks nation-wide used are analyzed, one of them is written in Turkish the other in English. These textbooks were written according to 2008-2009 education program’s curriculum. A qualitative oriented approach was employed and ethnographic content analysis was used as the methodological framework for this research as Irez (2006) has performed. Data were analyzed by means of boo...
